Which of the following correctly identifies the renal structures involved during the excretory phase?

The excretory phase refers to the stages involved in the removal of waste products and excess substances from the body by the kidneys. During this phase, the structures responsible for the transport and storage of urine play a crucial role.

The renal pelvis, ureters, and bladder are integral to the excretory system. The renal pelvis is the funnel-shaped structure that collects urine from the renal calyces and channels it into the ureters. The ureters are muscular tubes that transport urine from the kidneys to the bladder, which serves as a reservoir for urine before it is expelled from the body. This sequence of structures is vital for the proper functioning of the excretory system, facilitating the flow of urine from the kidneys to the external environment.

In contrast, the other options focus on different aspects of kidney function or anatomy. The renal corpuscles are involved in the filtration process of the blood and are not directly related to the excretion of urine. The renal arteries and veins are responsible for supplying blood to and from the kidneys, but they do not play a role in urine excretion. The renal tubules, while crucial for the reabsorption and secretion of substances during urine formation, are not the primary structures involved in the final stages of
